||'''Library Performance vs Importance'''<br>
+
||'''Overview'''<br>
*2,027 respondents from the undergraduate.In general, more than 75% of the undergraduate are satisfied and more than satisfied in library performance of the 4 segments – communication, facilities & equipment, information resources and service delivery. Out of the 3 satisfied ratings, very satisfied have the most respondents except for facilities & equipment.  
+
Based on the pyramid chart, we can learnt that there is high respondents from business and law that go to Kwa Geok Choo Library as compared to other study area. We also can see that there afew repondents from law will go Li Ka Shing Library. This could because that  Kwa Geok Choo Library is nearer to their study area and respondents preferred to go nearer libraries than travelling to a further library
*Comparing with importance:<br>
 
1.Communication and service delivery are the more consistent segments between their performance and importance. For example, communication performance satisfied metrics were 29%, 30%, 20% while the importance were 25%, 29%, 25%. Whereas, service delivery segment is moderate.<br>
 
2.However, facilities & equipment segment contribute to bigger gap such as more than 25% difference between their performance and importance in their highly satisfied ratings. Moreover, this segment shows more respondents that are dissatisfied in overall.

In the stacked column chart, respondents from information systems and econonmics have a higher percent of dissatisfactory. Library could find reach out to these study area to assisted them more or to understand their needs in order to cater for them.

SMU Library Survey

Background

Every two years, SMU Libraries conduct a comprehensive survey in which faculty, students and staff have the opportunity to rate various aspects of SMU library's services. The survey provides SMU libraries with input to help enhance existing services and to anticipate emerging needs of SMU faculty, students and staff.


Objectives

With the feedback obtain from the survey, I am tasked to utilize visual analytics approach to reveal the level of services provided by SMU libraries as perceived by:

  • the undergraduate students,
  • the postgraduate students,
  • the faculty,
  • the staff.

Summarising Data Set & Planning for Visualisation

The Dataset being used in this visualisation is from SMU Library: 2018 Survey Results. Can be found here

Dashboard Purpose Variable Require Measurement
Overview
This will be the home dashboard of the visualisation which summarise the entire processed data. It is interactive as viewer able to toggle filtering simply by selecting the field. This include:
  • Total number of respondents and the background of the respondents
  • Total respondents reponding to Li Ka Shing and Kwa Geok Choo Law Libraries respectively
  • Total respondents from different position such as Undergraduate/ Graduate / Staff/ Faculty
  • Total respondents from different study area such as Accountancy/ Business/ Economics
StudyArea, ResponseID, Position
Number of respondents
Importance VS Performance
This dashboard will provide an overview of respondents' response to libraries service. Rating their importancy and performance for different aspect. Presenting 1 being the lowest to 7 the highest. This will be a interactive interface where viewer able to toggle filtering to narrow down the details such as filtering through which library, which study area and their group position
Assessment Item, Score, HowOftenL, HowOftenW
Distribution of score rating 1 - 7, Number of respondents
Summary
This dashboard will provide an summary of the analysed data where viewer able to compare satisfactory between study area to on the general scale. This could acts as a medium for library to target specific study area to cater to their needs. It also allow viewer to see respondents relationship towards recommending to others based on their overall satisfactory
StudyArea, Number of Records, likelihood of recommend the library service to others
  • Satisfactory difference between study area
  • Correlation between people who are satisfied and people who likely to recommend to others

Overview

Based on the pyramid chart, we can learnt that there is high respondents from business and law that go to Kwa Geok Choo Library as compared to other study area. We also can see that there afew repondents from law will go Li Ka Shing Library. This could because that Kwa Geok Choo Library is nearer to their study area and respondents preferred to go nearer libraries than travelling to a further library

Among all the assessment item, availability of group work space was graded the lowest in term of performance. This could be an area that need to be improve or find out the reasons behind it.

3
Ss11.png

Among all the assessment item, availability of computer was graded the lowest in term of important. Libraries can consider removing it to cut expense or find others used for the computer.

4
Ss12.png

In the stacked column chart, respondents from information systems and econonmics have a higher percent of dissatisfactory. Library could find reach out to these study area to assisted them more or to understand their needs in order to cater for them.

5

In the correlation chart, we ca see that although respondents might be satisfied with the library services, there are some not willing to recommend it to others. This may because either the space not enough or they are more willing to spend their time alone in the libraries without any disturbance.
